What brand fuel for B7 V6 Highline?

[Lance B]

I have been using BP 98 Ultimate in my R36, but I have now got a B7 V6 Highline and I was wondering what others are using and what they believe is the best for this car? When I picked up my new B7 V6, the dealer used Caltex 98 Vortex and it went very well.

I use BP Ultimate and Caltex Vortex first, V Power third ... No real reason though, when 98 first appeared WRX retarded itself a touch more on Optimax (now Vpower) for some reason...

They are the three fuel cards I carry, so constrained to those three...

I didn't help much did I....

I use V-power most of the time but have also put in some Vortex on a few occassions. Didn't notice any difference to be honest...
